Non-standard metric screw thread geometry calculation
 |
Numerous applications require non-standard metric screw threads. Although non-standard screw threads should be avoided, when there is lack of an appropriate thread size many manufacturers (optical instruments, small size precision parts) use them. This article describes how to calculate such screw threads. |
Working with projection views
 |
The standard way to create an illusion of a 3-D image is to use the default drawing profiles or projection views. This article describes how to make these drawing profiles when your CAD program do not provide a preset function of projection views. |
Gear –Lever Mechanism
 |
The Gear- Lever Mechanism is a simple kinematical transducer. It converts the oscillation of the input lever to various oscillations of the output lever. It is named gear – lever because combines gear and lever motion. |
Designing with Thermoplastics
 |
Today's technology has introduced a variety of new materials for almost every application. The most common non-metallic materials in engineering are the thermoplastics. This article describes a few principles when designing with engineering thermoplastics. |
Simplified cardan-gear mechanism
 |
Cardan-gear mechanisms are expensive due to their internal gears. Because this cardan-gear mechanism uses only spur gear it is very simple in manufacturing and less expensive. |
Forcing split clamping elements
 |
The split clamping elements are using the pushing or pulling action of screws in order to clamp a part. The correct application of the screw force affects the efficiency of screw force during clamping. |
Using tension spring as a guiding element
 |
A tension spring except its use as an energy reserve element (power saver) can be useful in several applications due to its flexure capabilities. Such application is a flexible guiding element. |
Plain washers, standard and custom
 |
Plain washers are a basic machine component for almost any mechanical machinery. Although the plain washers exist in a huge variety, they must be customized in many applications. |
Guiding lines for part modelling
 |
The CAD software has changed the way components are designed in the last five years, but definitely one of the objectives for every designer is the design efficiency. Simple guide lines can save a lot of time in the designing and redesigning procedure. Read this article and learn how. |
Using fiber-optic technology for custom sensoring
 |
Although current automation industry has a huge variety of sensors for every application, there are times that seems no sensor can fit to a specific application. The fiber optic technology offers many simple and reliable solutions. |
